R: Reconstruction from Dual Wavelets

skeleton {Rwave} | R Documentation

## Reconstruction from Dual Wavelets

### Description

Computes the reconstructed signal from the ridge, given the inverse of the matrix Q.

### Usage

    skeleton(cwtinput, Qinv, morvelets, bridge, aridge, N)

### Arguments

`cwtinput` | continuous wavelet transform (as the output of cwt)
`Qinv` | inverse of the reconstruction kernel (2D array)
`morvelets` | array of Morlet wavelets located at the ridge samples
`bridge` | time coordinates of the ridge samples
`aridge` | scale coordinates of the ridge samples
`N` | size of reconstructed signal

### Value

Returns a list of the elements of the reconstruction of a signal from sample points of a ridge

`sol` | reconstruction from a ridge
`A` | matrix of the inner products
`lam` | coefficients of dual wavelets in reconstructed signal. They are the Lagrange multipliers lambda's of the text.
`dualwave` | array containing the dual wavelets.
